psxy (partially) ignores -Sq in segment headers

According to manual, setting -S in a segment header is supposed to work. But it doesn't for -Sq (annotated lines).

Put this on a file

> -Sql0.454/0.454/0.545/0.456:+lBlaBla
0	0
1	1

and this fails to annotate it.

gmt plot D.dat -JX15c/10c -Baf -BWSen -R-0.04/1.04/-0.04/1.04  -png lixo

But if we just add -Sq, it works (-S alone errors)

gmt plot D.dat -JX15c/10c -Baf -BWSen -R-0.04/1.04/-0.04/1.04  -Sq -png lixo

But there more issues in here. If we have a multi-word label, it must be wrapped under quotes, but than it no only prints the quotes too as it looses all after first word. That is: -Sql0.454/0.454/0.545/0.456:+l"Bla Bla"+v annotates "Bla
